Located on a vast rocky promontory at the crossroads of several valleys, the fortified village of Mont-Dauphin testifies to the power of Louis XIV. In 1692, as part of the War of the League of Augsburg (conflict between the Kingdom of France and the Jacobites (name given to the supporters of the dethroned Stuart dynasty in Great Britain) to a coalition of eight European sovereigns), the Duke of Savoy led a raid with an army of 40,000 men in the Durance Valley, in the heart of the Alps.  The cities of Guillestre, Embrun and Gap are looted and partially destroyed.Louis XIV then became aware of the lack of defense of the French kingdom on this Alpine border.
